Development of a hemodynamic database in severe trauma patients to define optimal goals and predict outcome

Noninvasive hemodynamic monitoring systems provide continuously monitored online displays of data from emergency department admission to the operating room and to the ICU for the early recognition of circulatory dysfunctions in acute emergency conditions. The net cumulative deficits of the cardiac index are estimated by thoracic electric bioimpedance, while arterial hypoxemia is measured by pulse oximetry and tissue perfusion is reflected by transcutaneous pO/sub 2/. Based on a large database, survival was satisfactorily predicted by discriminant analysis and by a new stochastic analysis and control program.
